Symbol Pin No. Type Functions Circuit configuration XIN XOUT 19 20 Xtal • Crystal oscillator connections (75 kHz) FMIN 12 Local oscillator signal input • FMIN is selected when the serial data input DVS bit is set to 1. • The input frequency range is from 10 to 250 MHz. • The input signal passes through the internal divide-bytwo prescaler and is inpu.
• High-speed programmable frequency divider — FMIN: 10 to 250 MHz ..Pulse swallower (divide-by-two prescaler built in) — AMIN: 2 to 40 MHz ......Pulse swallower 0.5 to 10 MHz ...Direct division
• IF counter — IFIN: 0.4 to 12 MHz ......For use as an AM/FM IF counter
• Reference frequency — Selectable from one of nine frequencies (crystal oscillator: 75 kHz) 1, 2.5, 3, 5, 3.125, 6.25, 12.5, 15, and 25 kHz
• Phase comparator — Supports dead zone control — Built-in unlock detection circuit — Built-in deadlock clear circuit — Sub-charge pump for fast frequency locking
• Built-in MOS transistor for .
